HORSESHOE-SWAGING MACHINE.

SPECIFICATION forming part of Letters Patent No. 331,626, dated December1,1885.

Application filed April 29, 1885.

To all whom it may concern:

Be it known that I, DAVID J. FARMER, of Penn Yan, in the county ofYates, in the State of New York, have invented new and usefulImprovements in Horseshoe Swaging Machines, of which the following,taken in connection with the accompanying drawings, is a full, clear,and exact description.

The purpose of this invention is to impart 1c the final finish tohorseshoes which have previously been bent and brought approximately toshape.

The invention consists, chiefly, in the employment of shoe-holding diesand swages 1 mounted on arotary carrier, and an oscillatory arm carryinga flattening and compressing die in position to impinge the horseshoecarried by the dies of the rotary carrier, and a rotary plating-die, allcombined with mechanism to produce a succession of action or operationon the metal in forming the shoe by the continuous movement in onedirection of the rotary carrier, and thereby save much time and producebetter results in the manufacture of horse- 2 5 shoes.

The invention also consists in novel means for guiding the die carriedby the oscillatory arm, so as to cause said die to bear with uniformpressure on the entire surface of the 0 horseshoe; and the inventionfurthermore consists in certain auxiliary devices employed in connectionwith the aforesaid rotary diecarrier and oscillatory arm, all ashereinafter more fully described,and specifically set forth 5 in theclaims.

The differentiating features of this invention over that described andshown in another application of even date herewith consist in themovement of the die and former carriers entailing differentorganizations of the machine.

In the annexed drawings,Figures1 and 2 are elevations of opposite sidesof my improved machine. Fig. 3 is an end view of the same, with aportion broken away to better illustrate 5 other parts situated at therear of said broken portions. Figs. at and 5 are vertical longitudinalsections taken, respectively, on lines no at and 3 3/, Fig. 3; and Fig.6 is a vertical transverse section on line .2 z, Fig. 5.

Similar letters of reference indicate corresponding parts.

Serial No. 163,862. (No model.)

A represents the supportingframe of the machine, said frame consisting,mainly, of two rigid parallel upright walls rising from a base or bedplate, by which latter it is firmly se cured in position. In said wallsarejournaled two shafts, B and B, one of which has affixed to it thedriving pulley or wheel WV, balancewheel W, and a pinion,V, which lattermeshes in a gear-wheel, U, fastened to the end of the other of theaforesaid shafts.

Between the two walls of the frame A is arranged a rotary die-carrier inthe form of a wheel, 0, fastened to the shaft 13, on which wheel aremounted the dies h and t, which 6 5 hold the horseshoe to be operatedupon, the central die, h, being fitted movably in a radial channel inthe wheel 0, and held yieldingly protruding at the periphery thereofsufficiently to hold the horseshoe which embraces the said die. The diei surrounds the die It, and is rigidly secured in a countersink in theface of the wheel 0, and serves to resist the pressure of the swagingand finishing die hereinafter described.

At opposite sides of the die tare jaws f, which yield laterally andendwise, and are adapted to press against thesides of the horse shoesheld on the die h. Said jaws are provided at their outer sideswith'cheeks or rollers g,which, in the rotation of the wheel 0,encounter cams G on theinner sides of the frame A, and thereby cause thejaws f f to be pressed against the sides of the horseshoe, as aforesaid,said pressure serving to swage or thick- 8 5 en up the heel of the shoeand prevent the shoe from spreading while subjected to the pressure ofthe flattening and compressing die. The flattening and compressing die(designated by the letter is in the drawings) is car- 0 ried inproximity to the aforesaid shoe-holding dies, so as to impinge and thusflatten the shoe simultaneously with the swaging of the same. The die Itis oscillated synchronously with the movement of the rotary carrier 0 by5 an arm, D, to which said die is secured, and which is arrangedradially to the wheel or rotary diecarrier 0, and hung on trunnionsjournaled in the side walls of the frame A, one of said trunnionsprojecting at the outside mo of the frame, and having affixed to it acrank,

H, which receives an oscillatory motion by a pitman, I, connecting saidcrank with awristpin, Z, on a wheel, L, fastened to the shaft 13, asshown in Fig. 20f the drawings.

In order to obtain auniform pressure of the flattening or compressingdie on the entire surface of the shoe held by the dies of the rotarycarrier 0, I make the oscillatory arm D flexible by providing it with ajoint, m, and aflixing to the lower section of said arm alaterally-projecting arm, E, the free end of which is connected with andsupported by the standards F F,which serve to guide the arm E, andthereby control in the line of motion the face of the die 70. Thestandards are arranged adjustably in relation to their distance from therotary carrier 0 by means of plates (2 d, fastened to the base of theframe A, and having avertical flange provided with a horizontal slot, e,for the reception of the pin or bolt by which the foot of the standardsis connected to said plate, as shown in Fig. 5 of the drawings. Theconnection of the arm E with the standards is also made adjustable byproviding the upper end of the standards with aslot, a, which isvertical, and through which the wrist-pin b of the aforesaid arm passes.Said slot allows the aforesaid connection to besihifted and secured inposition by nuts on the ends of the. wrist-pin b, so as to obtain theproper motion of the arm E, to carry the die It with uniform pressureacross the shoe held on the dies of the rotary carrier 0.

If desired, the arm E may be made self-adjusting to allow the die k toconform to the surface of the shoe by leaving the said arm loose on thestandard,and supporting it by springs c c in the slot (1, above andbelow the wrist-pin b. I do not, however, limit myself specifically tothe employment of the standards F, as shown, inasmuch as the arm E maybe supported by a hanger arranged above said arm.

M denotes a hub fastened to the shaft B in range with the wheel 0,andhaving secured to its periphery a die, a, which impinges and platesout the shoe carried by the wheel 0 during the rotation of the said huband wheel. A bar, N, is secured across the front of the frame A andarranged to sweep the completed horseshoe from the wheel 0, the shoebeing released from the holdingdie h by the retraction of said diecaused by a cam, P, on the inner side of the frame A,which cam isencountered by a roller, 0, on the end of a stud-pin projecting from theside of the die and through the wheel and jaw. The said bar Nalsoservesto press the side jaws, f, endwise even with the face of the dies,toclear the jaws from obstruction when the shoe is drawn off.

The operation of my invention is as follows:-

The shoe is placed by the operator on the die mounted on the rotarycarrier 0 in frontof the oscillatory die. Said carrier in its continuousmotion in one direction passes the first point of impulse given the sidejaws, f f, by the cams G, which swage the ends of the shoe, and at thesame time the oscillating arm D is carried into action, and the flat diethereof is brought to bear on the shoe toflatten or compress the surfacethereof. As the shoe is carried from the first and second action of themachine, the side jaws again receive the impingement of the cams G onthe sides of the machine. A second swaging of the shoe takes place, andin the further rotation of the die carrier or wheel the shoe and jawsare again brought between another set of the cams G, and then therotating plating-dien engages with the face of the shoe. At this pointthe operation is completed, and the shoe is subsequently dragged off bythe bar N. As there are several dies on the carrier or wheel, it isobvious that more than one shoe may be operated on during one revolutionof the rotary carrier.

If found desirable, the machine may be arranged to bend, crease, andfinish the shoe from the bar by applying suitable mechanism for bringingthe iron or straight blank in position for the former mounted on therotary carrier or wheel, and arranging creasingtools in the die carriedby the oscillating arm 1), or, if found preferable, may be arranged in arotary die, n, which completes the operation of forming the shoe.

Having described my invention, what Iclaim as new, and desire to secureby Letters Patent, 1s
